You added a position to a planners worksheet, and the manager is still to be hired - in the UI you can see this added in the sheet under position ID.
Why does the managers’ position ID appear as a number or an empty cell when downloading this sheet in Excel?
During an event, when you add a new position it has a new ID created. However, until this position is approved in the system, it means the position is still in draft, therefore the ID you see is not yet created in the system but only in draft.
Therefore if you download a report of a position that is assigned to a new position that is not approved, it will appear with a number and not by name.
